Metoro was using the same words, raua and tutu, at all three glyphs, in spite of their signs being different:

Eb7-8	Ea3-23	Ea3-24	Ea8-107
ko raua ka tutu	toki i te henua ku tutu raua		ko raua ku tutu i te henua

I believe that raua is the central part with tutu the two at left and right. By searching for these words in Metoro's reading of Keiti will get these additional glyphs:

Ea6-6	Ea7-3	Ea7-5	Eb8-7	Eb8-8
kua tuu ko raua	ka huki raua	ko raua	kua oho ku tutu
